What purpose do "Greek letters" serve in options trading?

• A. To measure the interest rates affecting options
• B. To quantify the sensitivity of an option's price to various factors
• C. To indicate the time until the option's expiration
• D. To analyze the credit risk associated with the underlying asset

Answer: (B)

In options trading, Greek letters play a crucial role in measuring and quantifying the sensitivity of an option’s price to various risk factors. Each Greek letter represents a different aspect of risk or sensitivity that can impact the option's price and its trading strategies. For instance, Delta, one of the most commonly referenced Greek letters, indicates how much the price of an option is expected to change for a $1 change in the price of the underlying asset. Gamma measures the rate of change in Delta, while Theta represents the time decay of the option. Vega measures the sensitivity of the option's price to changes in volatility. Rho indicates the sensitivity of the option's price to changes in interest rates. Understanding these sensitivities allows traders to make informed decisions about hedging, risk management, and setting their trading strategies appropriately based on market conditions. This measurable way of analyzing options enables traders to estimate potential gains and losses under various scenarios. Consequently, the essence of the correct answer lies in the comprehensive insight that Greek letters provide regarding how different factors influence the pricing of options, thereby aiding traders in their decision-making processes.
